Abstract

A razor blade member (46) has a first planar portion (60) and a second planar portion (62) connected to the first planar portion (60) by a transition bend region (66). The longitudinal edge (64) of the first planar portion (60) remote from the transition region (66) is sharpened to a cutting edge. The blade member (46) also includes stress balancing deformation (68,70) along the longitudinal length of the planar portions and adjacent the transition region (66). The bow (74) of the second planar portion (62) is less than 0.05 millimeter per centimeter length of blade member (46).
